title: Fresh vegetable intake and prevalence of diabetes in a Chinese population in Qingdao.
abstract: OBJECTIVE
  To investigate the association of fresh vegetable consumption with the risk of diabetes in a Chinese population.
  
  
  METHODS
  Data from 2386 individuals aged 35-74 years who participated in a population-based cross sectional diabetes survey in Qingdao, China were analyzed. Frequency of vegetable intake was obtained using a food frequency questionnaire. Diabetes was defined as self-reported diabetes or undiagnosed diabetes determined by 2-h 75 g oral glucose tolerance test or fasting capillary blood glucose test. Multivariate-adjusted odds ratio (OR) for the presence (vs. the absence) of diabetes in association with the frequency of fresh vegetable intake was estimated using logistic regression analysis.
  
  
  RESULTS
  The OR for the presence of diabetes was 1.17 (95% CI 0.66, 2.05) in men and 0.50 (95% CI 0.33, 0.77) in women who ate fresh vegetables more than 14 times/week as compared with those who ate fresh vegetables less than 7 times/week after adjustment for age, family history of diabetes, BMI, systolic blood pressure, 24-h energy intake, physical activity and smoking and drinking.
  
  
  CONCLUSIONS
  Consumption of fresh vegetables was associated with a low risk of having diabetes in women but not in men in this Chinese population.
